Why all the hate?

Re: Why all the hate? - Chris

Wait until you sell something on eBay, you post it to a confirmed address, the buyer receives it and give positive feedback....

And then, after a few weeks, the money used for payment is removed from your PayPal account due to a 'chargeback' initiated by the buyer or the card issuer. PayPal won't confirm who initiated it or the reason.

Then they'll ask for a whole slew of details, and the onus is on you to prove your innocence by providing verifiable proof of postage, even if this wasn't offered or even asked for as part of the eBay transaction. PayPal will not accept positive feedback given by the buyer as adequate proof of delivery and that you've acted by the book.

Also, I agree that either eBay and PayPal should be formally, properly merged, or eBay should be forced to accept any form of payment that is specified by the seller and acceptable to the buyer.
